' The main features of this application are disclosed in applicants contemporaneously pending application, filed January 16, 1911, Serial No. 602,862, to which reference is made, and certain aspects of the invention disclosed herein are disclosed and claimed in .applicants application filed September 3, 1.910, Serial No. 580,464.

In paperboxes of the character referred .to, and especially in the smaller boxes such as usedfor packaging cigarettes, etc., it is desirableto produce an article presenting an attractive appearance, and one which utilizes as much space as possible for the ,parts or elements on the interior of a box not only often results in the appropriation of space which might be utilized for the contents of the box, but often manifest themselves on the outer surface, especially when the box is made of relatively soft material, such as varieties of paper, etc. The elements of the box of the present invention as at 6, 6, so

are designed to present a nice appearance, and to take up a minimum of space consistent with their character, and to be associated in the production of complete boxes avoiding the objections above noted.

In the preferred embodiment of the invention, as illustrated, the boxes are of a polygonal rectangular or prismatic form, and it willbe apparent that though different forms of complete boxes are disclosed, yet the invention, viewed in some aspects, manifests itself in parts of a box of either form disclosed, or other forms.

The preferred type of box in which the invention is embodied is one comprising a head 1, a flange 2 secured around the head, and a collar or neck 3 within and closely fittin the. flange and therefrom, forming a shoulder 4. A sealripping cord 5 extends from the shoulder, being secured between the collar and the flange, and of suflicient length to lie along the shoulder beneath a seal or label strip which may fasten a top to the box. Upon pulling the cord the seal is broken andthe top may be turned back or removed. In the present embodiment the flange and the collar are each formed from blanks of superposed materials, and the flange and the collar are similar in several respects, as will appear.

In forming the collar a body strip or blank 5 of relatively thick paper, is provided, and its sides are preferably beveled or scarfed on opposite faces of the blank, and apart'from of the strip, providing two opposite edges that when the beveled portions are superposed an'd abutted the joint will be of the same thickness as the body material. At the portion of. the body strip designed to form the corners of the collar, grooves or scores 7 are made, preferably by removing the material of the body strip by means of rotary emery wheels having beveled or convex edges, so that the grooves have longitudinal 'walls' angularly' disposed relatively to each other, more clearly shown at 8, 9 in Fig. 9. Moreover, by forming the grooves in this manner the body material does not have to be. pressed to such a degree as might result ina bead or projection on the face of the strip opposite the grooves, which would tend to form a round or curved corner on the outside of the collar when the strip is folded, instead of a relativelv square corner, as by the present construction.

A strip of cover material 10 is provided with glue or other suitable adhesive throughout one, face, and its glued face is.. applied against'the unscored face of the body strip 5. the strip being of such width as to ex end beyond one side ed e of the body strip, as at 11, the other side of the projecting outwardly or outside the folding lines .strip,-and the front edge of the cover strip extends forwardly of the front edge 14 of the body strip so that it may be folded around the front edge of the body strip and adhesively secured to the scored face thereof, across the scores 7, as at 15. The- I I,

cover material is preferably glazed on the face which forms the outside of the collar, and is of thinner material than the body material, and when the two strips are assembled as stated, the cover provides a smooth ornamental surface for the collar. The cover strip is slit from its front edge to the edge of the body strip, as at 16, the slit being locate'd'at such a point as to provide a tongue 17 opposite the scarfed portion. In forming the collar the extended portion of the cover strip to the left of the slit 16, in Fig. l, is folded over the front edge of the body strip, the tongue 17 being unfolded; then the assembled blanks are folded at the scores into a continuous angular element, preferably a rectangular collar, the scores being on the'inside at the corners, and the soarfs or edges 6, 6, are overlapped terposition of adhesive to secure'the scarfed joint, the forward edges being in parallel relation. The disposition of the scores and relative width of the blank sections between and abutted, with the in-' the scores is such that the scarfed joint will midway the length cover strip will be in position folded over of the body strip which is trans-' that edge verse to the abutting edges 6, 6. Then the tongue 17, which will now be located opposite the joint formed by the abutting edges 6, 6, is'folded over the e go of the collar and against the inside t ereof, being secured by the adhesive on'the tongue. The tongue is of sufficient width to cover, when folded, the scarfed joint opposite thereto, and extend at either side of said joint and overlap the opposite side of the cover strip, thus concealing the body strip on the outside at the joint. and also-covering the joint to a considerable depth on the inside of the collar,- the inner side 17 of the tongue being, in this embodiment, intermediate the side edge of the body strip and the adjacent groove or folding line of the bodv strip. When the strips are folded the walls of the grooves'7 approach each other, and those portions of the cover strip facing the grooves are deflected toward the grooves and preferably thercinto so as to avoid bunching of 130 1 t "with one edge against the ter the grooves 1n the' cover' strip at the corners, the walls of the grooves in the completed collar being preferably spaced sufficiently to receive the cover strip, as shown in Fig. 9. Thus a relatively square orsharp corner is formed .on the inside and outside of the collar, the cover material on the inside being smoothly disposed at the corners. A collar formed in the manner related is shown in Fig. '5, m;

dividual steps in its formation being shown in Figs. 1, 2, 3 and l.

. In case a container or box is to be made, a flangeis made in a manner like that of the ferred to utilize the cover strip to secure the head ,to the flange. In this case the cover strip is extended rearwardly as well as forwardly of the body strip,

around the head,'the corners of the head entheflange, and the overbeveled joint of the flange is i g or as explained for formed in the-same way the collar. The rear extension of the cover in this embodiment, however, will extend below the head and is folded over against the head on each side and adhesively secured thereto, fastening the head and flange together. A box body formed in this manner is illustratedin Fig. 12, and embodies all the features of the collar except the flush V edge of cover strip and body strip.

When a box having a collar or neck is to be. produced,the collar is preferably formed separately from the box body, but each in the manner above described, the collar being of a size to closely fit within the flange of the box body, and these elements are assembled by sliding or telescoping the one with the other, resulting in the box illustrated in Fig.

. 8. Owing tothe relatively square corneron the inside of the flange, the relatively square I outside corners of the collar fit nicely at the corners of the flange, the cover strip of the collar closely fitting the folded portion" of the flange cover, which latter is smooth at the grooved corner as explained in connection with the collar, and it will be noted that by the smooth disposition of the cover strip on the inside of theflange,'the collar may readily slide into position, there being no bunches or protrusions. of the flange cover to be torn or rumpled, or which might tend I flange,

- to tearor rufli' up the collar cover on the out side. buitable adhesive is placed around the peripheral walls of the box on the inside oppositethe collar,-to secure the collar in the and one end of the ripping cord 4: is inserted between the collar and the flange and in contact with the adhesive, whereby but in the case of a flange it is pre-.

the collar, the flangeand the cord are efli ciently connected. The relative disposition of the elements of ,,thebox having a collar and a cord is illustrated in section in Fig. 9. The joint in the collar or the flange may be located at one corner of either'of said elements, if desired, without detracting from the efliciency of the construction. For example, in Fig. 10 is illustrated a collar blank having the grooves so disposed that when the blank is folded in the manner previously explained, the sides of the body strip meet, the edge of one side abutting the inside face of the other side and the body strip having no scarfs at its sides. The cover strip at one side isslitted in line with or slightly beyond the side edge of the body strip, as shown at 19, and the side of the cover strip is extended, as at 20, to provide sufficient material to coverthe exposed body material and overlap the other side of the cover strip when the blank is folded, as illustrated in Fig. 11

It is obvious that the box body of'Fig. 12 may have the joint formed at the corner in the same manner as illustrated in Fig. 11 without departing from the invention.

The construction described is found extraordinarily eflicient when embodied in flexible boxes or elements made of' flexible and relatively soft material, as referred to, and when the'boxes or elements are made automatically, as, for instance, by the machine described in the prior application, the

construction described offers special advan tages whereby the product is efficient and not liable to be defaced or destroyed while being made. c

As many changes could be made in the above construction and many apparently widely diflerent embodiments of this inven tion could be made without departing from the scope thereof, it is intended that all mat ter contained "in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
